Milwaukee 3/8" Thunderbolt Black Oxide Drill Bits - 48-89-2840 (6 Pack)

Heavy-Duty Performance for Professional Results

Power through metal, wood, and plastic with the Milwaukee 3/8" Thunderbolt Black Oxide Drill Bits. Engineered for long life and superior durability under heavy use, these bits feature the unique Thunderbolt tapered web — significantly thicker than standard bits — providing increased strength and protection against side-load breakage. Whether you're on a job site or tackling a weekend project, these bits deliver professional-grade results every time.

Key Benefits

• Thunderbolt Tapered Web: Thicker core resists breaking and provides extra durability under heavy side loads.
• 135° Split Point: Precision tip starts on contact to prevent "walking," ensuring cleaner, more accurate holes.
• 3-Flat Secure-Grip™: Prevents slipping in the chuck for better control and safety.
• Black Oxide Coating: Enhances lubricity, resists heat, and extends tool life with better chip ejection.
